Answer:
by reducing the frequency of the wave by a factor of three
Explanation:
Speed = wavelength * frequency.
Wavelength = speed/frequency
The speed of an electromagnetic wave in a vacuum is constant. Meanwhile the wavelength and frequency have an inverse relationship which means for every rise in any of the parameters there will also be a corresponding fall.
Since the wavelength is tripled then the frequency will also be reduced by a factor of 3
Answer:
Same magnitude of the 10 nc charge cause the electric field is external.
Explanation:
To do a better explanation, let's go and suppose we have an electric field of, 1300 N/C with a 10 nC charge.
As the system we are talking about is really big, and the charge is small, we can assume always if the charge is sitting right in the same point where the electric field is, then, the electric field would not suffer any kind of alteration in it's value. Therefore, no matter what value of the charge is sitting here, the electric field is independent of the charge, so it would not feel any alteration. However, the force that the charge is feeling would be stronger than in the first case.
F = qE
If charge is doubled, then the force would be bigger in the second case than in the first case, but electric field remain the same value.
It will move to the right and most likely a tiny bit down
Answer:
The change in the equilibrium melting point is 4.162 K.
Explanation:
Given that,
Pressure = 10 kbar
Molar volume of copper
Volume of liquid 
Latent heat of fusion 
Melting point =1085°C
We need to calculate the change temperature
Using Clapeyron equation
Put the value into the formula
Hence, The change in the equilibrium melting point is 4.162 K.
Electronic force related to magnitude by magnets. It is a magnetic force. So basically there is a big magnet in the center of earth. Keeps same energy. Right on edg
